I tried to reproduce the original test case. i.e. to type 'C'
(dired-do-copy) and select the "*Char Help*" buffer with C-x o.
The result is weird: the cursor in displayed in the minibuffer,
but the selected window is "*Char Help*". Here's a patch to fix this:
diff --git a/lisp/subr.el b/lisp/subr.el

After looking more at 'read-char-choice', it seems that special handling
of 'inhibit-keyboard-quit' and 'executing-kbd-macro' is not needed
anymore? And maybe also adding the 'minibuffer-prompt' face is not
needed too. Then what remains to do in 'read-char-choice' is to call
'read-char-from-minibuffer' and to show 'help-form-show' for 'help-char' key?
